  Click on the map to get a popup.  The popup is composed of a few basic elements: a container, a close button, and a place for the content.  To anchor the popup to the map, an <code>ol.Overlay</code> is created with the popup container.  A listener is registered for the map&#39;s <code>click</code> event to display the popup, and another listener is set as the <code>click</code> handler for the close button to hide the popup.
